Product description
Diffusion bonding means that first, two crystals are subjected to a series of surface treatments and then closely attached to each other to form an optical adhesive at room temperature. After that, the crystals are heat-treated to form a permanent bond without the need for other adhesives. Experiments show that when undoped crystals are bonded to both ends of a doped crystal of the same matrix as end caps, the temperature rise at the end faces is very small, close to the temperature of the coolant. This reduces the end-face distortion caused by the thermal lens effect and the thermally induced wavelength shift of the spectroscopic coating, which is beneficial to the stable operation of the laser and high-power laser operation. Therefore, this thermal bonding technology can not only greatly improve the thermal performance of the laser and the quality of the laser beam in laser applications but also contribute to the integration of the laser system and the obtaining of large-sized crystals.
